What is much more likely in my view is that the increasing dominance of FlyBe in the UK domestic market will be more robustly challenged, mainly because their fares, punctuality, and flight cancellation record is pretty woeful, especially when set against RYR/EZY.
I would question your comments about Flybe's punctuality. If you check recently reported CAA punctuality figures I think you'll find that Flybe is ahead of all large UK airlines including BA, RYR and EZY.
